PRINTING MECHANISM.

Application filed April 3, 1922. Serialy No.4 549,115.

To all 'whom t may concern.'

Be it known that I, CHENEY A. MCEAGH- RON, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have in' l0 will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a printingmechanism, by means of which several colors of a wall coating or finishing compound may 55 be 'applied to paper to represent what has been termed, opaline effects, that is, the appearance which a wall will have if the same is re eatedly touched with a brush at closely adjacent spots, the brush being supplied with the compound to be transferred to the wall, different colors of the compound being applied in the samevmanner one after the other. The printing mechanism which I have invented is for the printing of sheets of paper with the actual wall finishing compound for use in advertising the same, and

I have used it particularly in the applicationv of alabastine wall coverings to said paper for magazine advertising, though it is apparent that the use of the invention is in nowise thus limited. It is a primary object and purpose of the invention to provide a mechanism and process of printing by means of which the above stated enlls may be attained and the printing done with great rapidity, two or more of the colors being applied so as to obtain the opaline effect. A further object of the invention is to make a mechanism of this kind, and equip it with many novel features ofl construction for the eEective printing of the paper as outlined, mechanism being supplied for feeding the material that is needed in printing, and more particularly, equipping the machine with an exceptionally serviceable printing roller which automatically applies the compound to the paper in similitude to the brush touching process noted. These and many other novel features will appear as understanding of the'invention is had from the following description, taken in connection with the accompanying drawings, in which, y

Fig. 1 is a longitudinal vertical section taken through one end of the machine.

Fig. 2 isa like section through the oppo site end thereof.

Fig. 3 is an enlarged vertical section taken transversely throu hy the machine at. the point where one o the printing rollers is mounted.

Fig. 4 is a fragmentary enlarged vertical section taken longitudinally of the machine at said printing roller.

Fig. 5 is a fragmentary horizontal section taken substantially on the plane of line 5 5,

of Fig. 3,

Fig. 6 is an elevation looking at one side of the machine at one end thereof, and showing the means used for turning the printing and transfer rollers, and for operating the feeding mechanism, parts being broken away to better disclose the structure, and

Fig. 7 is a fragmentary side elevation showing the mountings for the several rollers.

Like reference characters refer to like parts in the several figures of the drawings.

In the construction of the machine, an elongated table v 1 is used of any required width, being carried on an under frame 2 which is supported by.. a plurality of posts 3 and 4. Posts 4 are wider than posts 3 and extend above the table, each being divided above the table to make a vertical slot between the parts 4a, the purpose of which will later appear. Rollers 5 and 6 are mounted horizontally at opposite ends of the table,

and an endless belt 7 passes over the table,

around the rollers, and under the table as shown. The table at a number of points in its length has a portion removed leavin wide slots or openings the full width thereo said openings occurring wherever the posts 4 are used. The construction illustrated' shows .but two of such openings but, if desired, the number may be increased. Rollers 9 and 10 are mounted horizontall between the pairs of posts 4, the u persi es of such rollers lying in the same p ane with the upper side of the table. The belt 7 runs over the rollers 9 and l() as shown.

A platform 11 is carried on posts 3 at one end of the machine and under the table (see Fig. 2), on which an electric motor 12 is supported. It drives suitable reduction gearing and other mechanism, lndlcated at 13, to in turn drive a chain 14 which passes around a sprocket wheel 15 secured 'ne end of the shaft 6a of roller 6, thus driving the roller and operating the belt at uniform speed.

The shaft 10a on which roller 10 is mounted at one end is equipped with two chain Wheels 16 and 17 and at its opposite Aend with a drum 18 in which a cam groove 19 is cut. The same construction is a plied to the shaft of roller 9, except that t e wheel 17 is left oif. In. fact the structure shown in Fig. 3, with this one exception, is identical with that above the roller 9, and a description for one will suiiice for both. Directly over the roller 10 a printing roller 2O is horizontally mounted, being covered with a natural sponge coverin shown at 21. The sponge has cavities an openings more or less irregularly placed throughout its entire surface, and is of a soft yielding nature, making it particularly applicable for the use -I have found for it in printing, escially as it is an exceptionally good absor nt of wall coatings dissolve in water, such. as alabastine and similar products. The printing roller is carried on a shaft 22, the endsJ of which have bearings in journal boxes 23 freely mounted in the vertical slots in posts 4, heretofore described. One end of shaft 22 is extended through its journal and equipped with three chain wheels 24, 25 and 26, `as seen in Fig. 3.

A .transfer roller 27 on a shaft 28, mountedin journal boxes 29 is located over the printin roller in contact engagement therewith. he shaft 28 is likewise extended at one end and equipped with a chain wheel 30. A second transfer roller 31 on shaft 32, mounted in boxes 33 lies above and in engagement with roller 27. A fourth transfer roller 34, on a shaft 35 passing through journal boxes 36 lies above and 1n contact with the roller 31. All of the journal boxes are freely received in the slots in the upper portions of posts 4. One end of the shaft 35, at the side of the machine op osite to that at which the different chain w eels described are located is equipped with a collar 37 with wh'ich the upper end of a lever 38 ivotally mounted between its ends on a racket 39 engages, the lower end of the lever having means entered into the cam groove 19 of drum 18. It is evident that with the rotation of roller 10, a reciprocatory movement is given to the roller 34, the same being moved back and forth over the roller 31 below. All of the transfer rollers have solid cores covered with a fabric covering, which-may be felt, or any other equivaient material.

Between two brackets 40 securedat the upper ends of posts 4, a trough like container 41 for the material used is located directl over the roller 34. At the undei side of t e trough, a cylindrical` member 42 is located, having a plurality of spaced apart holes 43 in its upper and lower sides oposite each other, a rod 44 bein located engthwise of the member 42 an having transverse openings 45 therethrough which are periodically brought into registry with the holes 43. A shaft 46 extends from the rod 44, passing through a suitable stutiin box 47 which precludes escape of the liqui said shaft at its outer end being equipped withfa chain wheel 48. A shaft 49 is mounted lengthwise of the container 41 on which a plurality of tufts of brush bristles 50 are secured, as shown, which serve to keep the material stirred and the openings 43 at the upper side of member 42 unobstructed. Shaft 49 is extended at one end and equipped with a chain wheel 51.

An en ess chain 52 passes around the wheels 25 nd 48. A second chain 53 passes around thewheels 26 and 51. A second chain wheel 54 is fixed to the roller shaft 6a (see Fig. 6) for driving an endless chain 55 which passes over wheel 30, thence downwardl against the opposite side of wheel 24 an then around wheel 16. It is evident that wheels 3() and 16 and their associated rollers are driven in the same direction and the wheel 24 and the printing roller in the opposite direction. A chain 56 is driven by wheel 17 and leads to the corresponding wheels 30, 24 and 16 of the printing ccnstruction associated with the roller 9 for driving the same.

An elongated sheet met-al cover or casing .57 is placed over the table beyond the print- 1n devices, across the upper portions of w ich a number of transverse burners 58 are located, for the burning of gaseous fuel. A protecting plate and delector 59 is placed under each burner to protect the belt and sheets of paper 66 passing thereunder and more or less evenly disseminate the heat throughout the space under the casings.

With a construction as described, the sheets of paper are laid on to the conveying belt -7 at the end of the machine where roller 5 1s mounted, the sheets being successively carried by the belt under the first rinting roller 2O from which one color of a abastine is printed on to the pa er. It will be evident that the mixed a abastine and water 1n the trough container 41 is fed by gravity periodically through the openings 43 and 45`onto the transfer roller 34 from which ying 57 and the water is dried so that when the. second printing mechanism is reached, 1t-1s 1n shape to pass therethrough to receive another color. vWhile I have shown but two of the printing devices in the machine, it is apparent that theA number ma be increased if more colors are to be printe After the second printing the sheet passes under the second casing 5i and is dried so that when it passes to the end of the machine it is ready to be placed ina pile with the others previously printed.

This machine is in practical use and has proven exceptionally satisfactory. With' it, sheets of paper may be fed rapidly through the rinting devices, receive a similitude of brus impressions of one color, be dried, and then recelve impressions of a different color, followed by a dryin of the sheet so that it is immediately ready for any further operations, such as cutting to size, packing and shipping, or the like. The invention is defined in the claims appended hereto and comprises all forms of construction and variations in constructive detail or method of operation that are comprehended by said claims.
